SDO_MODE (ENUM) ¶ TYPE SDO_MODE : Defines the different SDO transmission modes. Attributes: qualified_only InOut: Name Initial Comment AUTO ANYNUM_TO_INT(CS.SDO_MODE.AUTO) The client selects the mode automatically EXPEDITED ANYNUM_TO_INT(CS.SDO_MODE.EXPEDITED) The client uses the expedited protocol SEGMENTED ANYNUM_TO_INT(CS.SDO_MODE.SEGMENTED) The client uses segmented transfer protocol BLOCK ANYNUM_TO_INT(CS.SDO_MODE.BLOCK) The client uses block transfer protocol

TRANSITION_STATE (ENUM) ¶ TYPE TRANSITION_STATE : Describes the NMT state transitions for function block GET_STATE . Attributes: qualified_only InOut: Name Initial Comment START_REMOTE_NODE 16#5 Enter DEVICE_STATE.OPERATIONAL STOP_REMOTE_NODE 16#4 Enter DEVICE_STATE.STOPPED ENTER_PRE_OPERATIONAL 16#7F Enter DEVICE_STATE.PRE_OPERATIONAL RESET_NODE 16#6 Reset node RESET_COMMUNICATION 16#7 Reset communication ALL_EXCEPT_NMT_AND_SENDER 16#800 A flag for using in combination with another TRANSITION_STATE (logical OR). Must be used if NMT command should be addressed to all devices ( `` DEVICE``=0) but not to the NMT sender and NMT master (= CANopenManager).

NMT (FB) ¶ FUNCTION_BLOCK NMT EXTENDS CiA405Base This function block provides NMT services. The NMT request will be sent to the NodeID specified in input DEVICE . If NMT request should be addressed to all devices (including NMT master and sending device) set DEVICE to 0 . If all devices but not NMT master and sending device should be addressed use the additional flag TRANSITION_STATE.ALL_EXCEPT_NMT_AND_SENDER . InOut: Scope Name Type Initial Comment Inherited from Input NETWORK USINT 1 CAN network number the function block should operate on. Note: It is not the same like the network number in CANBus configurator. The CiA405 NETWORK is calculated by NetID + 1. Example: 1 = CAN0, 2 = CAN1, 3 = CAN2, … CiA405Base ENABLE BOOL FALSE Enables the function block on rising edge. Aborts operation on falling edge. CiA405Base TIMEOUT UDINT 0 Timeout in ms; 0 means no timeout CiA405Base Output CONFIRM BOOL FALSE TRUE : function block finished without error CiA405Base ERROR CANOPEN_KERNEL_ERROR CANOPEN_KERNEL_ERROR.CANOPEN_KERNEL_NO_ERROR Error code: see CANOPEN_KERNEL_ERROR for further details CiA405Base Input DEVICE DEVICE 0 NodeID of destination device (local or remote). 0 means all devices. STATE TRANSITION_STATE 0 The NMT transition which should be performed.

Input hReceiverId CAA.HANDLE receiver handle peError POINTER TO ERROR optional pointer to error enum

GetNetId (FUN) ¶ FUNCTION GetNetId : USINT Returns the NetID of a given message. InOut: Scope Name Type Comment Return GetNetId USINT NetID of hMessage . Input hMessage CAA.HANDLE handle of received message peError POINTER TO ERROR optional pointer to error enum

GetTimeStamp (FUN) ¶ FUNCTION GetTimeStamp : UDINT Returns the time stamp of a given message (if supported by CAN driver, else 0). InOut: Scope Name Type Comment Return GetTimeStamp UDINT Time Stamp of hMessage . Input hMessage CAA.HANDLE handle of received message peError POINTER TO ERROR optional pointer to error enum
